What I'm looking for

I'm looking to lead and build complex, high-quality mobile products across Flutter, Android, and iOS, with ownership from architecture through release and opportunities to apply AI-supported development workflows.

I've built production mobile applications at Systemhaus Ulm GmbH since 2017, covering technical conception, architecture, implementation, testing, maintenance, and releases for Android and iOS.

My work includes eb:fly, a CE-certified Flutter app used in Germany and Austria for epidermolysis bullosa, and Emendia MS, a CE-certified Class IIa medical device for multiple sclerosis patients integrating Roche Floodlight MS. I also delivered native patient and care apps with real-time communication, a modular Android patient-support app, and PrivateGPT, a locally hosted AI chatbot.

Since 2023, I've led a mobile team of up to four developers and introduced Flutter to unify the codebase and reduce development effort. Earlier, I designed app and web experiences at AvenDATA and developed Python NLP tools for machine translation at DFKI.
